Not really true for rapid tests. Rapid tests show positive for nucleocapsid which degrades pretty fast, so it's a reasonable indicator of live virus shedding (though likely not perfect either). You're likely referring to PCR which looks at RNA copies but cannot differentiate from fragments which may remain for some time. In my experience with many staff, I've seen staff remain positive of RAT for minimum 6, but as long as 13 days. My policy has been for employees to stay home until RAT negative
